As you are aware this case has for some time been moving towards increased action in Portugal on the basis of MPS 'International letters of request'. Whilst the process is more bureaucratic and slower than we would wish, you will recall at recent briefings that DAC Martin Hewitt has said that we were increasingly optimistic of that activity starting soon.

I am writing because I now believe that activity will occur in forthcoming weeks. You will understand that our requests for action in Portugal lead to investigative steps taking place under Portuguese law. In this context I have been discussing with my opposite number in the Policia Judiciara the high levels of interest that the action (especially when some of it will take place in public) will generate in the British media. I have discussed with him that it is our usual and preferred practice in this case to brief the media on an ongoing basis on such cases as that usually ensures that the activity of reporters and the coverage assists rather than damages the investigation.

These briefings, as you would appreciate, do not give complete detail on what the activity is, (as this could compromise what we are trying to achieve), but do provide context and as much information as possible whilst still protecting the investigation.

The advice I am receiving from Portugal is that their approach is very different and they do not brief the media on current investigations. He has been clear with me that if we provide any briefings or information on the work they are undertaking on our behalf, or if reporters cause any disruption to their work in Portugal, activity will cease until that problem dissipates.

It is important you understand this and appreciate the position in which I find myself. We will not be able to provide any information concerning the activity because ultimately it could mean the work stops. We respect the Portuguese position as we would expect them to respect our position if we were carrying out work on their behalf in the UK.

The most important task for me is to build momentum and protect our investigation given the many lines of enquiry that we see are necessary in order that we can do everything possible to solve the case. I ask that you support me and my team in those efforts. This includes respecting the requests of the Portuguese authorities during the work they will be carrying out on our behalf.

As well as being aware of the dangers of disrupting the work of the Portuguese, I would also ask you to think carefully about the information you decide to put into the public domain. Although we will continue not to comment on specific information, I would ask you to think twice about what impact that information or speculation might have on the investigation if it is published or broadcast.

We do not want to undermine our prospects of providing Mr and Mrs McCann with answers in this tragic case.

Collectively we all need to think carefully about our actions in this case.

I can't understand this promiscuity between the Police and the journos. No need of a mole when the MET is feeding the editors. And the way M.R. is apologising for not to being able to give, everyday, juicy informations to the tabloids!

Qoted on another forum, this post from a Portuguese citizen after this open letter to the editors :

"It sounds like the primary school teacher, organising a trip of the second-graders to the zoo. And we [the Portuguese] are the exotic animals..."
